Title: Identify the structures, functions, and surgical pathologies of the heart.
Course: Surgical Technologist I (14056-I) > Section: Understanding Structures, Functions, and Surgical Pathologies of Body Systems

Identification should include

- the location, structures, and functions of the heart
- the process and paths of blood circulation
- the cardiac cycle
- the electrical conduction system
- coronary circulation
- the relationship of the autonomic nervous system and the heart
- pathologies (e.g., blockages, arrhythmias, pacemaker/defibrillator issues).

Process/Skill Questions:

- In what ways is the heart similar to two pumps working side by side?
- What are the “lub-dup” heart sounds? How are they related to cardiac function?
- How is heart rate related to the size and activity level of the patient? What are the implications of this relationship for the surgical patient? For the surgical team?
- What is the relationship between the electrical condition system of the body and normal sinus rhythm?
- What is the underlying principle of a pacemaker? A defibrillator? How can each improve the quality of life for a patient?
